lower mowers, pull back to raise mowers.
Manual Mode - Set mow switch (Q) in its OFF (down)
position. In this position all mowers will raise or lower
while pressure is applied to the lift lever.
Automatic Mode - Set mow switch (Q) in its ON (up)
position. In automatic mode the mowers will lower and
start automatically with a momentary forward movement
of the lift lever. In this mode mowers will only raise to a
“crosscut” position with a momentary backward
movement of the lift lever.
To raise mowers to their transport position, hold lever
until mowers are fully raised.
Q. PTO Switch
The PTO switch is a 2-position knob type switch
used to engage and disengage the mowers. It

switch to turn lights on. Press rear portion of
switch to turn lights off.
S. Traction Control
Pressing switch enables controller traction
control system. This system reduces down
pressure on decks by pulsing the lift circuit,
transferring weight to mower. Reducing down
pressure improves traction, but may cause
decks to float up creating an uneven cut.
To increase down pressure on decks, let go of switch.
This reduces traction, but improves deck contact with
ground.
T. Engine Throttle
Controls engine speed. Run machine at full throttle
during normal machine operation.
U. Cruise Control (Option)
When switched ON the cruise control will
lock the traction pedal in its current position.
Cruise will unlock when switched OFF, or if
parking brake is applied.
V. Ignition Switch
The ignition switch has four positions. OFF-
RUN (ON) - GLOW PLUG - START. In the
RUN position the controller program is
running and input and output circuits are
being monitored. The GLOW PLUG position
has no function for this mower. See Section
5.4 and Parts & Maintenance Manual.
W. Hour Meter
Records engine operating hours. Use
the hour meter to schedule periodic
maintenance.
X. Fuel Gauge
Indicates current fuel level. Check fuel
gauge daily before starting machine.
Y. Warning Lights
Alerts the operator to conditions
requiring immediate action. See Section
4.4.
Z. Engine Coolant Temperature Gauge
Indicates engine coolant temperature.
Normal operating temperature should be
between 160° - 230°F (71°-110°C). If
temperature rises above 230° (110°F),
alarm will sound for 5 seconds, then beep
once every three seconds. See Section
4.4.
NOTICE
The warning light will remain on as long as a low oil level
is detected. If the alarm sounds due to low oil level, it can
be disabled by turning switch (O) to OFF.
NOTICE
While in an Automatic Mode lift or lower cycle, which
lasts approximately 3 seconds, moving the lift lever in the
opposite direction will turn all mowers off, and manual
mode will start for the position selected.

5.6 TO DRIVE / TRANSPORT____________________________________________________
Read and follow all safety notes contained in this manual
when driving or transporting mower. When operating in
reverse look behind you to ensure you have a clear path.
Important: If this mower is driven on public roads, it must
comply with federal, state and local ordinances. Contact
local authorities for regulations and equipment
requirements.
To raise mowers to their transport position:
Set PTO switch to OFF. Pull mower lever back. Hold lever
until mowers are up and lift arms are in their fully raised
(transport) position.
Important: The mow switch should be OFF while
transporting mower.
5.7 MOWING_________________________________________________________________
To mow:
1. Set PTO switch to its ON (Up) position. This also sets
the mower lever to automatic mode. [See 4.3].
2. Press mower lever forward momentarily to lower
mowers. Mowers will begin turning automatically when
cutting units have lowered.
3. To lift mowers, pull mower lever back and release.
Mowers will stop turning and raise to their crosscut
position. To lift mowers to their transport position
continue to hold lever until mowers are completely
raised.
4. Activate traction control (S) as required to improve
weight distribution between decks and mower. [See
4.3].
Always mow with the engine at full throttle.
To install mulching plate:
An optional mulching plate can be used instead of the rear
discharge chute. Do not operate mower without rear
discharge chute or mulching plate installed.
1. Place PTO switch in OFF (down) position, lower mowers
to the ground, engage parking brake and stop engine.
2. Remove three nuts securing discharge chute to mower
housing.
3. Remove discharge chute and assemble mulching plate.
Secure with three nuts removed previously. Store the
discharge chute in a safe location for future use.
5.8 MOWING SPEED __________________________________________________________
Cutting quality is better at speeds well below the transport
speed of the mower. An initial mow speed of 6 to 7 MPH (10
to 11 kph) is set at the factory and should be satisfactory for
most cutting conditions. Local turf conditions, however, may
respond better to a different speed. If an adjustment is
needed, refer to the Parts and Maintenance manual.
WARNING
To prevent serious injuries, keep hands, feet, and
clothing away from cutting unit when the blades are
moving.
NEVER use your hands to clean cutting units. Use a
brush to remove grass clippings from blades. Blades
can be sharp and could cause injuries.
DO NOT operate mowers without rear discharge
chutes or mulching plate installed.
!
OPERATION 5

5.9 TOWING / TRAILERING _____________________________________________________
If the mower experiences problems and must be shut down
and removed from the area, it should be loaded onto a trailer
for transport. If a trailer is not available, the unit can be
towed slowly for short distances.
Use care when loading and unloading mower. Fasten mower
to trailer to prevent mower from rolling or shifting during
transport.
Long Distance Trailering / Transport. If the mower is to
be trailered on the highway, before strapping to trailer,
close fuel shut off valve and inflate tires to maximum
pressure listed on side of tire. Reduce tire pressure to
normal after removing from trailer. [See 5.10].
Before towing, open tow valve. The tow valve permits
moving the mower without starting the engine and prevents
possible damage to hydraulic components.
The tow valve (A), is located on the hydraulic drive pump
beneath the operators seat. Remove cover from floor in front
of operator’s seat. To open valve, use a wrench or insert a
pin or small screw driver into the small hole in the valve
stem. Turn the valve counterclockwise one full turn.
Before towing make sure cutting units are raised. If they
cannot be raised, remove them from the mower.
Close valve completely and replace cover after towing.
Figure 5B
5.10 HILLSIDE OPERATION _____________________________________________________
The mower has been designed for good traction and stability
under normal mowing conditions. Use caution when
operating on slopes, especially when the grass is wet. Wet
grass reduces traction and steering control.
1. Always mow with the engine at full throttle, but reduce
forward speed to maintain the proper cutting frequency.
2. Activate traction control (S) as required to improve
weight distribution between decks and mower. [See
4.3].
3. If the mower tends to slide or the tires begin to mark
the turf, angle mower into a less steep grade until
traction is regained or tire marking stops.
4. If mower continues to slide or mark the turf, the grade
is too steep for safe operation. Do not make another
attempt to climb, and back down slowly.
5. When descending a steep slope, always lower
implements to the ground to reduce the risk of mower
overturning.
Correct tire pressure is essential for maximum traction.
Front ......................... 16 psi (111 kPa)
Rear.......................... 12 psi (86 kPa)
NOTICE
Do not exceed 2 MPH (3.2 KPH) while towing. Long
distance towing is not recommended
.
A
LF006
WARNING
To minimize the possibility of overturning, the safest
method for operating on hills and terraces is to travel up
and down the face of the slope (vertically), not across the
face (horizontally). Avoid unnecessary turns, travel at
reduced speeds, and stay alert for hidden hazards.
CAUTION
Do not operate this mower on slopes greater than 20°.

c. Do not spray water directly at the instrument
panel, or any electrical components.
d. Do not spray water into the cooling air intake or
the engine air intake.
3. Fill mower’s fuel tank at the end of each operating day
to full mark on fuel gauge.
Always use clean, fresh #2 diesel fuel. Minimum
Cetane Rating 45.
4. Handle fuel with care - it is highly flammable. Use
an approved container; the spout must fit inside the
fuel filler neck. Avoid using cans and funnels to transfer
fuel.
5. Store fuel according to local, state or federal
ordinances and recommendations from your fuel
supplier.
6. Never overfill or allow the tank to become empty.
7. Inspect hydraulic hoses and tubes daily. Look for wet
hoses or oil spots and replace worn or damaged hoses
and tubes before operating the machine.
8. Check the engine oil and hydraulic oil at the start of
each day, before starting the engine. If the oil level
is low, remove the oil filler cap and add oil as
required. Do not overfill.
9. After engine has cooled, check coolant level.
Radiator should be full and recovery bottle should be
up to the cold mark.
10. Park machine in designated area. Engage parking
brake and remove key. Place key in a secure
location to prevent unauthorized use of equipment.
11. Check the engine oil and hydraulic oil at the start
and end of each day. If the oil level is low, remove
the oil filler cap and add oil as required. Do not
overfill.
NOTICE
Do not wash a hot or running engine. Use
compressed air to clean the mower, engine and
radiator fins to reduce the potential for corrosion and
moisture contamination.
WARNING
Never remove the fuel cap from the fuel tank, or add fuel,
when the engine is running or while the engine is hot.
Do not smoke when handling fuel. Never fill or drain the
fuel tank indoors.
Do not spill fuel. Clean spilled fuel immediately.

or any device that may create sparks and ignite the fuel
or fuel vapors.
Be sure to reinstall and tighten fuel cap securely.
!
WARNING
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks; use paper
or cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin, it must be surgically removed within a few
hours by a doctor familiar with this form of injury or
gangrene may result.
WARNING
To prevent serious bodily injury from hot coolant or
steam blow-out, never attempt to remove the radiator
cap while the engine is running. Stop the engine and
wait until it is cool. Even then, use extreme care when
removing the cap.
Do not pour cold water into a hot radiator. Do not operate
engine without a proper coolant mixture. Install cap and
tighten securely.
